The total cost for the rental is calculated by subtracting the first 50 miles from the total miles driven (430 miles) and then multiplying it by the per mile rate ($0.35/mile).

Miles is a unit of distance measurement. It is used for measuring the distance between two places. It is equivalent to 1.609 kilometers. Miles are used for measuring the length of roads, flight distances, distances between cities, and other large distances. Miles can also be used to measure the length of running, swimming, and cycling events. Miles are also used in the United States to measure the speed of vehicles, such as cars and airplanes.

This gives us a total cost of $118.50 for the miles driven. To calculate the total cost for the rental, we add the cost for the miles driven ($118.50) to the daily rate for the 2 days ($46.90 x 2 days = $93.80). This gives us a total cost of $212.30 for the rental.

The intervals at which the parabolic equation from the graph is decreasing is (4, ∞).

A parabolic equation is an equation of a curve usually in form of a U-shape when displayed on the graph. In the given diagram, we can use the standard form of a quadratic equation y = ax² + bx + c as the starting point for finding the equation through the three points of the curve.

Using the following points on the curve; (0,-2) (4,6), and (6,4), because these points pass along the x and y-axis of the curve.

Create a system of equations by substituting the x and y values of each point into the standard formula of a quadratic equation to create the three-equation system.

−2 = a(0)² + b(0) + c,

6 = a(4)² + b(4) + c,

4 = a(6)² + b(6) + c

Solve the system of equations to find the values of a, b, and c.

[tex]$$a= - \dfrac{1}{2}$$, b = 4, c = -2[/tex]

Substitute the actual values of a, b, and c into the formula for a quadratic equation to find the resulting equation.

The consistent state lattice x is equivalent to (0.6, 0.9), and the stochastic matrix P is normal.

To decide if a stochastic grid P is standard, we should initially compute the consistent state matrix x of the Markov chain with a matrix of change probabilities P. To do this, we set up the situation Px = x and address for x.

We can communicate the components of x as far as a boundary t as follows:

x1= 0.5t + 0.1

x2= 0.5t + 0.9

We can then settle for t in view of the amount of x1 and x2. The amount of x1 and x2 ought to be equivalent to 1, so:

0.5t + 0.1 + 0.5t + 0.9 = 1

t = 1

Therefore, The consistent state lattice x is equivalent to (0.6, 0.9).

The average rate of change of the function in the interval [ 4 , 9 ] is given by the equation m = -67

The average amount that a function changed per unit during that time period is the rate of change of that function. It is calculated using the slope of the line connecting the interval's endpoints on the graph of the function.

Rate of change = f ( b ) - f ( a ) / ( b - a )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 4 , -84 )

Let the second point be Q ( 9 , -419 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

The rate of change of the function = slope

Slope m = ( -419 - ( -84 ) ) / ( 9 - 4 )

On simplifying the equation , we get

Slope m = ( -419 + 84 ) / 5

Slope m = -335/5

Slope m = -67

As per the intersecting point, the length of AC is 4x + 10.

The diagonals of a rectangle are two lines that intersect at the midpoint of the rectangle. In this case, the diagonals of rectangle ABCD intersect at point E.

If AE = 2x + 5 and BD = 5x + 2, then we can calculate the length of AC. We know that AC is the sum of AE and ED, so AC = AE + ED.

Since the diagonals of a rectangle intersect at the midpoint of the rectangle, AE and ED are equal. Therefore, AC = 2x + 5 + (2x + 5) = 4x + 10.

Therefore, the length of AC is 4x + 10. Knowing the lengths of the diagonals can help us find the length of the sides of the rectangle, and can also be useful in finding the area of the rectangle

The first hiker is 2 miles east and 1 mile north of the starting point, so the position can be represented by the coordinate pair (2, 1).

What is the Pythagorean theorem in plain English?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. The Perpendicular, Base, and Hypotenuse are the names of the three sides of this triangle.

The second hiker is 2 miles west and 3 miles south of the starting point, so the position can be represented by the coordinate pair (-2, -3).

The Pythagorean theorem can be used to calculate the separation between the two points:

d = √((2 - (-2))²  + (1 - (-3))² ) = √((2 + 2)² + (1 + 3)²) = √(4² + 4²) = √(16 + 16) = √32

The complete question is as follows:

The expected number of flips to get a string of r heads in a row, given that the probability of getting heads in each flip is p.

Probability is a scale between 0 and 1 that represents the possibility of an event happening. An event with probability 1 is guaranteed to happen, while an event with probability 0 is impossible. The number of favorable outcomes divided by the total number of potential outcomes in the sample space yields the probability of an event A, commonly denoted as P(A). The sample space, for a fair six-sided die, is the set of all potential outcomes, such as 1, 2, 3, 4, 5, and 6. The probability of rolling a 4 is 1/6. Numerous disciplines employ probability to make predictions, deduce conclusions, and make judgments in the face of uncertainty.

We can use a recursive formula to find the expected number of flips X.

Let X_i be the expected number of flips to get a string of r heads in a row, starting from the i-th flip. Then, X_i can be expressed in terms of X_{i+1}:

X_i = (1 - p) + p(1 + X_{i+1})

Here, (1 - p) represents the case where the i-th flip results in tails, and p(1 + X_{i+1}) represents the case where the i-th flip results in heads and we have to continue flipping until we get a string of r heads in a row.

To find the expected number of flips X, we need to sum over all X_i, starting from the first flip:

E[X] = X_1 = (1 - p) + p(1 + E[X])

Solving for E[X], we get:

E[X] = 1/(1 - p)

This formula gives us the expected number of flips to get a string of r heads in a row, given that the probability of getting heads in each flip is p.

Hence our required solution is ,

___________________________________

[tex] 4. \begin{cases} 2x + 4y = -10 \dots (1)\\\\ -7x -y = 22(2)\end{cases}[/tex]

Taking equation 2 ,
